so me and my guy, we were fooling around and i only had my panties on he was naked, and his pre cum or ejaculatory semen whatever landed on me and we decided to cool it down a little, then things became intense so i went naked also, he rubbed his penis on me all over my vulva, his penis felt dry but i was wondering if the sperms were dead or alive and if i can get pregnant if they were still alive and if i should take a morning after-pill for precautionary measure. we are both virgins and we decided to try orals for the first time that night too, my throat feels weird should i be worried
